Control in applications such as electric and hybrid vehicles, solar power and other high power electronic systems relies on current sensing and Hall effect devices are a popular technology for this purpose. With these kind of applications in mind, Melexis engineers designed an improved MLX91209CA high-speed linear Hall IC that achieves a response time of 3µs.
The MLX91209BA has a programmable magnetic sensitivity of 10 to 150mV/mT and the MLX91209CA has 5 to 150mV/mT. With these programmable sensitivity ranges, the sensors are suitable for measuring DC and AC currents up to 200 kHz.
